Installing the display
11 Place the display facedown near the top of telephone and align the two
mounting holes of the display with the two mounting holes of the
telephone.
12 Insert two self-tapping Phillips-head screws from the faceplate into the
mounting holes; tighten them firmly with a #1 Phillips screwdriver.
Note: Do not allow R5 on the power supply board to become bent
during this procedure.
13 Install the power supply board. See Procedure 2 on page 93.
14 Fold the ribbon cable near the connector to align with the J2 pins on
the display board, ensuring that the notch on the ribbon cable is facing
toward the display board. Carefully work the ribbon cable connector
onto the J2 pins until it is firmly seated. Route the cable flat beside the
power supply board, gathering excess cable under the display. Be
careful not to press the cable beneath the alignment posts or studs of
the base. See Figure 37 on page 110.
15 Replace the base. If the telephone is equipped with an MPDA or MCA,
reconnect the data cable to the base telephone jack and replace the
footstand (ensuring that the MPDA or MCA cable does not get pinched
between the base and footstand). Make sure the footstand is firmly
seated to the base.
16 Tighten all the screws, reconnect all cords, and place the telephone in
the normal operating position.
Note: Place the label supplied with the display on the outside of the
bottom cover of the telephone. This allows proper identification and
tracking of the option level of the set.
17 Perform the self-test (see Procedure 1 on page 32) and acceptance
test procedures. See LD 31 in the Software Input/Output Guide
Administration (553-3001-311).
